Property Value
Type: System.Windows.UIElementThe UIElement that is the logical parent of the ToolTip control. The default is null.
You can position a ToolTip by setting the PlacementTarget, PlacementRectangle, Placement, HorizontalOffset, and VerticalOffsetProperty properties. These properties behave the same as they do for a Popup. For more information, see Popup Placement Behavior.
The following example shows how to create and position a ToolTip.
<Ellipse Height="25" Width="50"
Fill="Gray"
HorizontalAlignment="Left"
ToolTipService.InitialShowDelay="1000"
ToolTipService.ShowDuration="7000"
ToolTipService.BetweenShowDelay="2000">
<Ellipse.ToolTip>
<ToolTip Placement="Right"
PlacementRectangle="50,0,0,0"
HorizontalOffset="10"
VerticalOffset="20"
HasDropShadow="false"
Opened="whenToolTipOpens"
Closed="whenToolTipCloses"
>
<BulletDecorator>
<BulletDecorator.Bullet>
<Ellipse Height="10" Width="20" Fill="Blue"/>
</BulletDecorator.Bullet>
<TextBlock>Uses the ToolTip Class</TextBlock>
</BulletDecorator>
</ToolTip>
</Ellipse.ToolTip>
</Ellipse>
//Create an ellipse that will have a //ToolTip control. Ellipse ellipse1 = new Ellipse(); ellipse1.Height = 25; ellipse1.Width = 50; ellipse1.Fill = Brushes.Gray; ellipse1.HorizontalAlignment = HorizontalAlignment.Left; //Create a tooltip and set its position. ToolTip tooltip = new ToolTip(); tooltip.Placement = PlacementMode.Right; tooltip.PlacementRectangle = new Rect(50, 0, 0, 0); tooltip.HorizontalOffset = 10; tooltip.VerticalOffset = 20; //Create BulletDecorator and set it //as the tooltip content. BulletDecorator bdec = new BulletDecorator(); Ellipse littleEllipse = new Ellipse(); littleEllipse.Height = 10; littleEllipse.Width = 20; littleEllipse.Fill = Brushes.Blue; bdec.Bullet = littleEllipse; TextBlock tipText = new TextBlock(); tipText.Text = "Uses the ToolTip class"; bdec.Child = tipText; tooltip.Content = bdec; //set tooltip on ellipse ellipse1.ToolTip = tooltip;
